FIG. 1 illustrates a system 100 for capturing primary and auxiliary dataassociated with items. Example items include products in a retailfacility. Primary data associated with such items can include productidentifiers such as Universal Product Codes (UPCs), which may be encodedin an indicium such as a barcode affixed to an item or stored in a radiofrequency identification (RFID) tag affixed to the item. Another exampleof primary data includes a weight of the item. A further example ofprimary data includes an indication of the presence of an ElectronicArticle Surveillance (EAS) tag affixed to the item.

The system 100 includes a data capture device 104 configured to capturethe above-mentioned primary data. The data capture device 104 canprovide the primary data to a host computing device 108, for example viaa network 112, which can include any suitable combination of local andwide-area networks. The host computing device 108 can include, forexample, a point-of-sale (PoS) computing device configured to furtherprocess the primary data. Such processing can include retrievingadditional information (e.g. a price) from a database stored at, orotherwise connected with, the host computing device 108. Suchinformation can be presented on a display of the host computing device,printed on a receipt, and the like.

The host computing device 108 can also be configured to perform otherfunctions that employ data beyond the primary data mentioned above,referred to as auxiliary data. For example, the host computing device108 can be configured to implement at least one item recognitionmechanism, for example to detect the type of an item when the item doesnot carry a product identifier (e.g. encoded in a barcode or RFID tag).Another example function that uses auxiliary data includes storing animage of the surroundings of the data capture device 104 at the timethat the primary data was captured, e.g. for security purposes.

The auxiliary data includes image data in the examples discussed herein,although in other examples the auxiliary data can include other types ofdata in addition to, or instead of, image data. Implementing functionsthat use auxiliary data can be costly in terms of computational andstorage resources. Therefore, the system 100 enables selective captureof auxiliary data that may mitigate the above-mentioned computationaland storage costs.

The data capture device 104 includes a controller such as a centralprocessing unit (CPU), also referred to as a processor 116interconnected with a non-transitory computer readable storage medium,such as a memory 120. The memory 120 includes any suitable combinationof volatile memory (e.g. Random Access Memory (RAM)) and non-volatilememory (e.g. read only memory (ROM), Electrically Erasable ProgrammableRead Only Memory (EEPROM), flash). The processor 116 and the memory 120each comprise one or more integrated circuits (ICs).

The processor 116, as will be discussed in greater detail below,controls various data capture sensors of the data capture device 104 tocapture the above-mentioned primary and auxiliary data. The processor116 also determines, based on captured primary data, when to captureauxiliary data. In particular, the processor 116 executesmachine-readable instructions stored in the memory 120 and referred toherein as a data capture control application 124 (or simply as theapplication 124) to perform the above functionality. Execution of theapplication 124 configures the processor 116 to capture and provideprimary data to the host computing device 108, and also to determine,based at least in part on a repository 128 stored in the memory 120,whether to trigger the capture of auxiliary data.

The repository 128 contains registration indicators corresponding to atleast one event for which detection criteria are defined in theapplication 124. When a given event is detected and is associated with aregistration indicator in the repository 128, the processor 116initiates the capture of auxiliary data.

In other examples, the contents of the repository 128 can be integratedinto the application 124. In addition, the functionality discussedherein need not be implemented via the execution of a singleapplication. In other examples, the memory 120 can store at least oneapplication enabling the processor 116 to control the data capturesensors mentioned earlier. Such an application may expose, via anapplication programming interface (API) or the like, event identifiersto an additional application that determines when to capture auxiliarydata.

The above-mentioned data capture sensors include at least one primarydata capture sensor and at least one auxiliary data capture sensor. Inthe illustrated example, the data capture device 104 includes threeprimary data capture sensors, including a primary image sensor 132, aweigh-scale 136 (also referred to simply as a scale 136), and ashort-range communications assembly 140. Other examples of primary datacapture sensors include a laser-based barcode scanner (e.g. instead of,or in addition to, the primary image sensor 132), an infrared sensor andthe like.

The auxiliary data capture sensor, in the illustrated example, is anauxiliary image sensor 144. The auxiliary image sensor 144, in thisexample, is a color image sensor, while the primary image sensor 132 canbe a black and white image sensor. Further, the auxiliary image sensor144 may have a greater resolution than the primary image sensor 132.

The data capture device 104 also includes a communications interface148, enabling the data capture device 104 to exchange data with othercomputing devices, such as the host computing device 108. Thecommunications interface 148 includes any suitable hardware (e.g.Network Interface Controllers (NICs), Universal Serial Bus (USB)controllers, and the like) allowing the data capture device 104 tocommunicate over the network 112.

The above-mentioned components of the data capture device 104 can beimplemented in various form factors. Turning to FIG. 2 , an example datacapture device 104 is shown in the form of a bioptic scanner that can bemounted in a retail checkout countertop or other support surface.

In the example illustrated in FIG. 2 , the data capture device 104includes a housing 200 containing the components mentioned above inconnection with FIG. 1 . The housing defines a platform 204 on whichitems may be placed and over which a scan volume 206 is defined, e.g. byscan windows 208 and 212. The scale 136 is coupled to the platform 204,and the primary image sensor 132 has a field of view extending from atleast one of the windows 208 and 212. The data capture device 104 caninclude an optical assembly enabling the primary image sensor 132 tocapture images via either window 208 and 212, or the data capture device104 can include two primary image sensors, with respective fields ofview traversing the scan windows 208 and 212.

The auxiliary image sensor 144 is also disposed within the housing 200such that a field of view of the auxiliary image sensor 144 extends fromone of the scan windows 208 and 212. In other examples, however, theauxiliary image sensor 144 can be contained in another housing separatefrom the housing 200, and communicatively coupled with the processor 116(within the housing 200). In further examples, the auxiliary imagesensor 144 can deployed along with an auxiliary controller distinct fromthe processor 116, and an auxiliary communications interface (e.g. a USBinterface) distinct from the interface 148. In such implementations, theauxiliary controller can communicate with both the processor 116 and thehost computing device 108.

As will be apparent to those skilled in the art, primary data capturemay be initiated by passing an item through the scan volume 206, placingan item on the platform 204, activating an input of the device 104, orthe like. Turning now to FIG. 3 , the actions performed by the datacapture device 104 during primary data capture operations in order tocontrol auxiliary data capture will be described in greater detail.

FIG. 3 illustrates a method 300 of selective auxiliary data capture. Themethod 300 will be described below in conjunction with its performancein the system 100, and in particular by the data capture device 104. Itis contemplated, however, that the method 300 can also be performed invarious other suitable systems.

At block 305, the data capture device 104 is configured to obtain eventregistrations. The data capture device 104 stores (e.g. within theapplication 124) event detection criteria corresponding to a pluralityof events. When the detection criteria for a given event are satisfied,the processor 116 generates an event identifier, which may be processedin various ways.

Various events and corresponding detection criteria are contemplated.For example, when an indicium such as a barcode is detected in an imagecaptured by the primary image sensor 132, and data is successfullydecoded from the barcode, the data capture device 104 can be configuredto transmit the decoded data to the host computing device 108. The hostcomputing device 108, in turn, can be configured to return a “scandisable” command to the data capture device 104. The scan disablecommand instructs the data capture device 104 to pause primary datacapture, e.g. for a predefined period of time (e.g. one second, althoughshorter and longer time periods are also contemplated) or until a resumecommand is received from the host computing device 108. Processing ofdecoded data by the host computing device 108 may consume more time thanthe next capture operation at the data capture device 104. The scandisable command can therefore be employed to enable the host computingdevice 108 to complete processing of the decoded data before the datacapture device 104 sends additional decoded data. Various other exampleevents and detection criteria associated therewith will be describedbelow.

An event registration is associated with a specific event, and is anindication that when that event occurs (i.e. when the detection criteriadefining that event are satisfied), the data capture device 104 is tocapture auxiliary data for provision to the host computing device 108.In other words, event registrations indicate which events the hostcomputing device 108 is subscribed to. The event registrations arestored in the repository 128 in the present example. For example, therepository 128 can contain registration indicators in the form of eventidentifiers of events to which the host computing device 108 issubscribed. In other examples, the repository 128 can contain each eventidentifier, and a flag associated therewith indicating whether or notthe host computing device 108 is subscribed to that event.

The event registrations can be obtained at block 305 at the time ofdeployment of the application 124 to the data capture device 104 (thatis, the event registrations can be hard-coded at the data capture device104). In other examples, the event registrations can be received fromthe host computing device 108 separately from deployment of theapplication 124, e.g. in a request via the network 112. In furtherexamples, in which the auxiliary image sensor 144 is associated with adistinct auxiliary controller and auxiliary communications interface,the event registrations can be stored in a memory connected to theauxiliary controller rather than in the repository 128. That is, thehost computing device 108 can pass event registrations to the auxiliarycontroller via the auxiliary communications interface.

At block 310, the data capture device 104 is configured to control atleast one of the data capture sensors mentioned above to capture data.For example, the processor 116 can enable at least one of the primaryimage sensor 132, the scale 136 and the short-range interface 140.

Enabling the primary image sensor 132 may include capturing a stream ofimage frames at a suitable frequency and evaluating each frame accordingto the event detection criteria mentioned above.

At block 315, the data capture device 104 is configured to determinewhether any of the event detection criteria mentioned above aresatisfied by the data captured via the primary data capture sensors atblock 310. When the determination at block 315 is affirmative the datacapture device 104 proceeds to block 320 to process the captured data.When the determination at block 315 is negative, the data capture device104 can discard the data captured at block 310, and repeat theperformance of block 310 to capture further data. As indicated by thedashed line from block 320 to block 315, a single capture of data atblock 310 may also be evaluated more than once for event criteria. Inother examples, block 320 can precede block 315.

As noted earlier, various forms of event criteria can be evaluated atblock 315. Turning to FIG. 4 , an example method 400 of implementingblocks 315 and 320 is illustrated. In particular, the method 400implements two sequential instances of blocks 315 and 320. At block 405,the processor 116 determines whether an indicium such as a barcode, QRCode, Digimarc or the like has been detected in a frame of image datacaptured via the primary image sensor 132. When the determination atblock 405 is negative, the processor 116 returns to block 310 (i.e. anegative determination at block 405 is equivalent to a negativedetermination at block 315).

When the determination at block 405 is affirmative, the processor 116proceeds to block 410. In other examples, the processor 116 can performblock 410 regardless of the determination at block 405. In furtherexamples, following an affirmative determination at block 405 theprocessor 116 can generate a “Decode” event before proceeding to block410. The Decode event indicates that an indicium has been detected anddecoded at block 405, and can also be employed to trigger the capture ofauxiliary data.

At block 410 the processor 116 determines whether the image captured atblock 305 via the primary image sensor 132 is sufficiently similar to apreceding image (e.g. the previous captured frame from the primary imagesensor 132). Various mechanisms for measuring similarity between imagesmay be implemented at block 410, including those based on featurematching (with an affirmative determination resulting at block 410 whenthreshold number or proportion of matching features are detected betweenthe current and previous frames).

In other examples, the processor can perform the determination at block410 by determining whether the code detected in the captured frame atblock 405 is a new code. A new code is one that does not match apreceding code (i.e. detected in the previous frame of image data fromthe primary image sensor 132), or that matches a preceding code when atimeout period has expired (e.g. 2 seconds, although other time periodscan also be employed). Whether a detected barcode is new or notindicates whether a different item has been placed in the scan volume206. Detection of a new code at block 410 results in a negativedetermination. When the code is not new, the determination at block 410is affirmative, indicating that the item in the scan volume 206 is thesame item as in the preceding image frame, rather than a different item.

Following an affirmative determination at block 410, the processor 116may be configured not to send data decoded from the barcode to the hostcomputing device 108 (because such data was already sent in connectionwith the previous image frame). However, the processor 116 can beconfigured to generate an “Imager Stable” event and proceed to block320. An “imager stable” event indicates that the item present in thescan volume 206 is the same as a previously detected item. The eventindicates that the item is currently stable within the scan volume 206and therefore that imaging via the auxiliary image sensor 144 may befeasible. As will now be apparent, an affirmative determination at block405 followed by a negative determination at block 410 is an exampleimplementation of block 315 in which the event criteria for the “imagerstable” event is satisfied. The performance of block 320 following suchan event can include updated a most recently detected barcode indicatorin the memory 120.

When the determination at block 410 is negative, indicating that thebarcode detected at block 405 is different from the preceding codedetected from primary image data, the processor 116 proceeds to block415. At block 415, which represents an example implementation of block320 as shown in FIG. 3 , the processor 116 can send the data decodedfrom the new barcode to the host computing device 108.

Following the transmission at block 415, the processor 116 determines,at block 420, whether a “scan disable” command has been received fromthe host computing device 108. As will now be apparent, the performanceof block 415 represents an additional implementation of block 315 (i.e.another evaluation of event detection criteria). When the determinationat block 420 is negative, the data capture device 104 can simply returnto block 310, or can repeat block 420 until a timeout period is reached.

When a scan disable command is received, leading to an affirmativedetermination at block 420, the processor 116 proceeds to block 320,where processing of the scan disable command can include interruptingimage capture and/or decoding processes.

Returning to FIG. 3 , following the performance of block 320, forexample according to the implementations discussed above in connectionwith FIG. 4 , the processor 116 is configured, at block 325, todetermine whether the event or events detected at block 315 areregistered events. That is, the processor 116 is configured to determinewhether the event identifier of the event detected at block 315 appearsin the repository 128 as an event to which the host computing device 108is subscribed. In examples in which the auxiliary image sensor 144 isassociated with a distinct auxiliary controller that stores eventregistrations as mentioned earlier, the determination at block 325 canbe performed by the auxiliary controller instead of the processor 116.That is, the processor 116 can be configured to simply pass all eventdetections from block 315 to the auxiliary controller, and the auxiliarycontroller can assess whether each event is a registered event at block325.

When the determination at block 325 is negative, the processor 116returns to block 310 to capture further data via the primary datacapture sensors. When the determination at block 325 is affirmative,however, the processor 116 proceeds to block 330. At block 330, theprocessor 116 controls the auxiliary image sensor 144 to capture animage frame, and sends the captured image frame to the host computingdevice 108. In other examples, the auxiliary image sensor 144 operatesin a video mode, and therefore captures a stream of image framesthroughout the performance of the method 300. In such examples, at block330 the processor 116 is configured to retrieve the most recent framecaptured by the auxiliary image sensor 144 and transmit the retrievedimage frame to the host computing device 108. The processor 116 thenreturns to block 305. In other examples, in which the auxiliary imagesensor 144 is associated with a separate auxiliary controller, theauxiliary controller performs block 330, controlling the auxiliary imagesensor 144 to capture an image for transmission to the host computingdevice 108 via the auxiliary communications interface.

Turning now to FIG. 5 , another example implementation of block 315 isillustrated as a method 500, which can be performed simultaneously withthe implementation shown in FIG. 4 , or instead of the implementationshown in FIG. 4 . In the implementation shown in FIG. 5 , the datacaptured at block 305 includes data generated by the scale 136 (e.g. amass of an item on the scale, in any suitable unit).

At block 505 the processor 116 is configured to determine whether thedata received from the scale 136 indicates a non-zero weight. That is,the processor 116 determines whether an item is present on the platform204. When the determination at block 505 is negative because the datafrom the scale 136 indicates zero weight (or a weight below aconfigurable threshold), the processor 116 returns to block 310.

When the determination at block 505 is affirmative, at block 510 theprocessor 116 determines whether a variance in the signal from the scale136 falls below a threshold. The threshold applied at block 510 isselected such that variance below the threshold indicates that the itemon the platform 204 is substantially stationary. Variance above thethreshold indicates that the item is in motion, and that it maytherefore not currently be feasible to obtain an accurate weight or tocapture an auxiliary image of the item. For example, the threshold caninclude a time period (e.g. 0.5 seconds, although other time periods mayalso be employed) and a maximum permitted change in the data receivedfrom the scale 136 over the time period (e.g. 1 gram, although variousother permitted changes can also be employed).

When the determination at block 510 is negative, indicating that theitem is in motion, the processor 116 can repeat block 510, or simplyreturn to block 310. When the determination at block 510 is affirmative,the processor 116 proceeds to block 320, and then to block 325, asdiscussed above.

FIG. 6 illustrates a further example implementation of block 315illustrated as a method 550, which can be performed simultaneously withthe implementation shown in FIG. 4 , or instead of the implementationshown in FIG. 4 . In the implementation shown in FIG. 6 , the datacaptured at block 305 includes data generated by the short-rangecommunications interface 140. Such data can include a proximityindicator, which can be determined from various parameters including asignal strength measurement. An example of a signal strength measurementused to generate the proximity indicator is a Received Signal StrengthIndicator (RSSI) representing the detected signal strength of a nearbyRFID tag, EAS tag, or the like. Such data can also include an identifieror other data encoded in the above-mentioned tags, which can be receivedat the interface 140.

At block 555 the processor 116 is configured to determine, from aproximity indicator based on an RSSI value and/or other suitableparameters generated from a tag transmission or reflection, whether theproximity indicator exceeds a threshold selected to indicate thepresence of a nearby tag. When the determination at block 555 isnegative, the processor 116 returns to block 310. In other examples, thedetermination at block 555 includes a determination of whether theproximity indicator has exceeded the threshold continuously for at leasta threshold time period (e.g. 1.5 seconds, although shorter and longertime periods are also contemplated). Such a determination indicates thatthe wireless tag has remained near the data capture device 104 for thetime period, rather than having been detected as the wireless tag iscarried past the data capture device 104.

When the determination at block 555 is affirmative, at block 560 theprocessor 116 determines whether a tag identifier has been received. Inother words, the determinations at block 555 and 560 assess whether anRFID or EAS tag is not only close enough to the short-range interface140, but also whether an identifier or other payload data from the taghas been retrieved by the data capture device 104.

When the determination at block 560 is negative, the processor 116 canrepeat block 560, or simply return to block 310. When the determinationat block 560 is affirmative, the processor 116 proceeds to block 320,and then to block 325, as discussed earlier.

The repository 128 (or, in other implementations as mentioned earlier,an auxiliary controller associated with the auxiliary image sensor 144)can contain a plurality of event registration indicators. That is, anapplication executed by the host computing device 108 can subscribe tomore than one event. Further, multiple events may occur simultaneously,or at least within a certain time period. Under such conditions, thedata capture device 104 can simply capture and send auxiliary data tothe host computing device 108 for each registered event. However, thismay result in redundant auxiliary data being sent to the host computingdevice 108. Therefore, in some examples the repository 128 can alsoinclude priority indicators for each registered event.

Turning to FIG. 7 , example contents for the repository 128 is shown,including two registration indicators 700-1 and 700-2 identifying the“scan disable” event mentioned earlier, as well as a “stable weight”event detected via the method 500. In addition, the repository 128includes a priority indicator 704-1, 704-2 corresponding to eachregistration indicator 700. When two or more events are detected atblock 315 within a configurable time period (e.g. 0.5 seconds), theprocessor 116 may be configured to assess only one of the events atblock 325 according to the priority indicators 704. Thus, in the exampleshown in FIG. 6 , only the scan disable event would be processed atblock 330.

The repository 128 can also include additional data, for example tospecify auxiliary data capture parameters. For example, each eventregistration can specify different capture parameters (e.g. exposuretime, flash and the like) for controlling the auxiliary image sensor144. In other examples, the data capture device 104 can include multipleauxiliary data capture sensors, and different event registrations canconfigure the processor 116 to activate different ones of the auxiliarydata capture sensors.

In further variations, the host computing device 108 itself can performblocks 325 and 330. In particular, rather than the processor 116 or theauxiliary controller associated with the auxiliary image sensor 144storing event registrations, the host computing device 108 can maintainthe event registrations. The processor 116 can simply report alldetected events to the host computing device 108, and the auxiliaryimage sensor 144 (e.g. via the auxiliary controller and communicationsinterface) can provide a stream of images, e.g. for storage in a bufferat the host computing device 108. The host computing device 108 is thenconfigured to determine whether an event reported by the processor 116corresponds to an event registration, and to retrieve a relevant framefrom the above-mentioned buffer when the even does correspond to anevent registration.
